Place Voting files in Quorum failgroup or Regular failgroup ?
QUORUM disks, or disks in quorum failure groups, cannot contain any database files,
the Oracle Cluster Registry (OCR), or dynamic volumes. However, QUORUM disks
can contain the voting file for Cluster Synchronization Services (CSS). Oracle ASM
uses quorum disks or disks in quorum failure groups for voting files whenever
possible.
To sum up, i think the different between a regular failgroup and a quorum failgroup is a quorum failgroup can only contain vote files and a regular one can contains multiple kinds of files.
So i didn't see any advantage to place voting files on a quorum failgroup than on a regular one. Why Oracle introduce the concept of quorum failgroup ?
